Research ArticleOpen accessEvery word in the titleGenetic Complementation Studies of Human Pin1 in Azotobacter vinelandii Revealed that it Requires Amino Terminus of the NifM to Deliver PPIase Effect to the Fe-protein of NitrogenaseKumaraguru Raja, Lakshmi Pulakat, Nara GaviniThe NifM is a peptidyl prolyl cis-trans isomerase and is required for the maturation and activation of the Fe protein of Nitrogenase. Since the carboxyl terminus of NifM is similar to the Human Pin1, we expressed the Human Pin1 in A. vinelandii BG98, a nifM mutant strain containing a kanamycin insertion and found that it could not complement the function … …American Journal of Biochemistry and Biotechnology, Vol. 2, Issue 1 · 31 Mar 2006 · 6,708 accessesView PDFCite
Research ArticleOpen accessIn the keywordsGenetic Diversity in Cichla monoculus (Spix and Agassiz, 1931) Populations: Implications for Management and ConservationCarlos Henrique Dos Anjos Dos Santos, Carolina Fernandes Silva De Sousa, Maria de Nazare Paula-Silva et al.Problem statement: The object of this study was to examine the genetic structure and gene flow in Cichla monoculus populations in seven varzea lakes of the Solimoes River using Randomly Amplified Polymorphic DNA (RAPD) markers, to monitor the region where petroleum is transported in the Amazon basin. Approach: The loss of genetic diversity is one of the main factors leading … …American Journal of Environmental Sciences, Vol. 8, Issue 1 · 30 Jan 2012 · 8,517 accessesView PDFCite
Review ArticleOpen accessIn the abstractGenomic Regions and Candidate Genes Associated With Semen Traits in Rams: A Systematic GWAS Review With Implications for South African Sheep BreedsNhlakanipho Sam Zulu, Khoboso Christine LehloenyaRam fertility is a key determinant of reproductive efficiency in sheep production systems, particularly under extensive and semi-extensive conditions prevalent in South Africa. Semen quality traits, including ejaculate volume, sperm concentration, motility, and cryotolerance, exhibit measurable genetic variation and are increasingly investigated using genomic approaches. This systematic review synthesizes evidence from three eligible Genome-Wide Association Studies (GWAS) analyses that have … …American Journal of Animal and Veterinary Sciences, Vol. 21, Issue 3 · 26 Oct 2026 · 50 accessesView PDFCite
Literature ReviewOpen accessIn the abstractPhenotypic, Reproductive and Genomic Perspectives on the Status and Research Gaps of South African Bosvelder SheepNhlakanipho Sam Zulu, Khoboso Christine Lehloenya, Khanyisile Hadebe et al.The South African Bosvelder sheep is an emerging composite sheep developed from indigenous Bapedi and commercial White Dorper and Van Rooy sheep. Despite its reported adaptability and production potential under bushveld conditions, the sheep remains scientifically under-characterized and is not formally recognized within national breeding frameworks. This narrative review evaluates the current state of knowledge regarding phenotypic, reproductive, and genomic … …American Journal of Animal and Veterinary Sciences, Vol. 21, Issue 2 · 1 Jul 2026 · 1,242 accessesView PDFCite
Review ArticleOpen accessIn the abstractGoats’ Litter Size Concerning Bone Morphogenetic Protein 15 Gene VariationsTebogo Letsukulo Percy Thepa, Thobela Louis Tyasi, Jones Ng’ambiBone morphogenetic protein 15 (BMP15), a member of the transforming growth factor-β (TGF-β) superfamily, plays essential roles in follicular development and ovulation. Single nucleotide polymorphisms (SNPs) in the BMP15 gene have been associated with litter size in multiple livestock species, yet no comprehensive systematic review has synthesized findings across goat breeds. This systematic review aimed to evaluate the association between … …American Journal of Animal and Veterinary Sciences, Vol. 20, Issue 4 · 18 Feb 2026 · 1,405 accessesView PDFCite
Research ArticleOpen accessIn the abstractHacking Back: Using Genetic Algorithms to Outsmart HackersGhosoun Al Hindi, Mohammad Alshraideh et al.Web applications are widely used in today's digital landscape, necessitating robust security measures to protect against unauthorized access by malicious users. Ensuring the security of these applications requires effectively identifying and addressing vulnerabilities. This paper proposes an automated methodology for vulnerability detection, utilizing a genetic algorithm to generate test cases, which offers greater efficiency and performance compared to resource-intensive and … …Journal of Computer Science, Vol. 21, Issue 9 · 10 Oct 2025 · 2,600 accessesView PDFCite

To delve into the current research landscape concerning peanut disease and pest control, this study adopts a bibliometric methodology and employs a VOS viewer for multidimensional visualization … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 4 · 5 Nov 2024 · 4,034 accessesView PDFCite
Literature ReviewOpen accessIn the abstractSystematic Review of Single Nucleotide Polymorphisms of Cattle Beta-Lactoglobulin Gene and their Association with Milk Production TraitsThlarihani Cynthia Makamu, Thobela Louis TyasiThe application of molecular genetics technology to pinpoint certain DNA markers associated with commercially significant features is highly anticipated since it has the potential to enhance the effectiveness of breeding programs by selecting young animals early for use as future breeding stock. One of the main genes expressed in bovine milk is the Beta-Lactoglobulin Gene (βLG), and its polymorphism can … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 2 · 4 Mar 2024 · 5,811 accessesView PDFCite
Research ArticleOpen accessIn the abstractIn vitro Polyploid Induction in Phalaenopsis Aphrodite by PendimethalinPrasetyorini Djarot, Deden Sukmadjaja, Fadya Annisa Chaesarani, SukonoPhalaenopsis aphrodite is a type of orchid with high ornamental and economic value. However, its development for commercial needs in Indonesia is still hindered by the limited availability of varieties. Therefore, enhancing genetic diversity is necessary, one of which is through polyploid induction.
